EMUC1 & EMUD1 pin-pair, as well as the EMUC2 & EMUD2 pin-pair, for alternate

debugging channels. This functionality has been provided by the DIP switches in S3

(for Motor Control family) and S4 (for Sensor and General-Purpose families).

Table 14-3 shows the various alternate debugging channel options available to the

user. These switches are represented in the schematics in Figure A-5: “dsPICDEM™

2 Development Board Schematic (Sheet 4 of 7)”.

14.1.5

LCD

The LCD supports 2 rows and 16 columns of ASCII-text characters and is controlled by

a dsPIC30F2011 device. The dsPIC30F devices may write ASCII character data and

cursor position information via an SPI interface to the LCD controller. Header H1 con-

nects the SPI pins (SCK1 and SDO1) on the dsPIC30F device to the LCD controller. A

pair of jumpers should be installed on H1 to connect any one of the following to the

LCD:

- 28-pin device on U2B1

- 40-pin device on U2A1

- 18-pin device on U1C1

- 28/40-pin device on U1A1 or U1B1
